The front surface opening of the water injection port 200 located in the water injection channel 250 serves as a water injection port 251 . The deflector 170 faces the water injection port 251 .
在洗涤剂盒110的前部的上方配置有接水室230a。洗涤剂盒110的虹吸机构部S1位于多个流出口234的正下方的位置即来自流出口234的水的落下位置与洗涤剂盒110的溢水口118之间。在盖部142，于比虹吸帽141向落下位置侧伸出的部分存在倾斜面143。流入室230b的两个排出口235位于比洗涤剂盒110的溢水口118靠注水路250的上游的位置。A water receiving chamber 230 a is disposed above the front portion of the detergent box 110 . The siphon mechanism part S1 of the detergent box 110 is located between the overflow port 118 of the detergent box 110 and the position directly below the several outflow openings 234, ie, the position where the water from the outflow openings 234 falls. In the cover part 142, the inclined surface 143 exists in the part which protrudes to the drop position side rather than the siphon cap 141. As shown in FIG.

The discharge port 243 of the water path 240 a is located in the water injection path 250 .
全自动洗衣机1中进行各种运转模式的洗涤运转。在洗涤运转中，依次执行清洗过程、中间脱水过程、漂洗过程以及最终脱水过程。根据运转模式，有时会进行两次以上漂洗过程和中间脱水过程。The fully automatic washing machine 1 performs washing operations in various operation modes. In the washing operation, a washing process, an intermediate dehydration process, a rinsing process, and a final dehydration process are sequentially performed. Depending on the operation mode, the rinsing process and the intermediate spin process may be performed twice or more.
在清洗过程和漂洗过程中，在洗涤脱水桶22内蓄有水的状态下，波轮24向右方向和左方向旋转。通过波轮24的旋转而在洗涤脱水桶22内产生水流。在清洗过程中，通过产生的水流和水中所含的洗涤剂来清洗洗涤物。在漂洗过程中，通过产生的水流来漂洗洗涤物。During the washing process and the rinsing process, the pulsator 24 rotates in the right direction and the left direction when water is stored in the washing and dehydrating tub 22 . The rotation of the pulsator 24 generates water flow in the washing and dehydrating tub 22 . During the washing process, the washing is washed by the generated water flow and the detergent contained in the water. During the rinsing process, the laundry is rinsed by the generated water flow.
在中间脱水过程和最终脱水过程中，洗涤脱水桶22和波轮24一体地高速旋转。通过洗涤脱水桶22中产生的离心力的作用，洗涤物被脱水。During the intermediate dehydration process and the final dehydration process, the washing and dehydration tub 22 and the pulsator 24 are integrally rotated at high speed. The laundry is dehydrated by centrifugal force generated in the washing and dehydrating tub 22 .
在洗涤运转开始前，从注水口部200拉出投入盒100，分别向洗涤剂盒110和柔顺剂盒120投入运转一次的量的液体洗涤剂和液体柔顺剂。Before starting the washing operation, the injection box 100 is pulled out from the water inlet portion 200, and the liquid detergent and the liquid conditioner are injected into the detergent box 110 and the conditioner box 120 respectively for one operation.
投入到洗涤剂盒110内的洗涤剂在清洗过程的供水时被供给向洗涤脱水桶22。此时，在洗涤剂盒110内，主动由洗涤剂生成洗涤剂泡沫，生成的洗涤剂泡沫与洗涤剂一起被供给向洗涤脱水桶22。The detergent put into detergent box 110 is supplied to washing and dehydrating tub 22 during water supply in the washing process. At this time, detergent foam is actively generated from the detergent in detergent box 110 , and the generated detergent foam is supplied to washing and dehydrating tub 22 together with the detergent.
图7的(a)和(b)是示意性地表示用于对从洗涤剂盒110向洗涤脱水桶22的洗涤剂的投入动作进行说明的洗涤剂投入装置50的主要部分的图。(a) and (b) of FIG. 7 are diagrams schematically showing main parts of detergent injecting device 50 for explaining the action of injecting detergent from detergent box 110 into washing and dehydrating tub 22 .
在清洗过程的供水时，第一供水阀61开放，通过第一供水路63向注水口部200供水。When water is supplied in the cleaning process, the first water supply valve 61 is opened, and water is supplied to the water filling port 200 through the first water supply channel 63 .
如图7的(a)所示，供给至注水口部200的水从设于接水室230a的顶面的供水口221向接水室230a落下并被接水室230a承接。此时，落下的水冲入水面，由此，接水室230a内的空气与水混合而在蓄留的水之中产生无数气泡。As shown in (a) of FIG. 7 , the water supplied to the water inlet 200 falls from the water supply port 221 provided on the top surface of the water receiving chamber 230a to the water receiving chamber 230a and is received by the water receiving chamber 230a. At this time, the falling water hits the water surface, whereby the air in the water receiving chamber 230a mixes with the water to generate countless air bubbles in the stored water.
含有气泡的水从多个流出口234流出，向洗涤剂盒110内流下。流下的水与蓄于洗涤剂盒110内的洗涤剂撞击。洗涤剂因撞击的水的冲击而起泡。此时，水中所含的气泡加入到洗涤剂中，由此促进起泡。由此，在洗涤剂盒110内生成大量的洗涤剂泡沫。Water containing air bubbles flows out from the plurality of outflow ports 234 and flows down into the detergent box 110 . The falling water collides with the detergent stored in detergent box 110 . Detergent foams from the impact of the impinging water. At this time, air bubbles contained in water are added to the detergent, thereby promoting foaming. As a result, a large amount of detergent foam is generated in detergent box 110 .
未从流出口234流出的接水室230a内的水流入到流入室230b内，从流入室230b的排出口235向注水路250排出。如此一来，接水室230a内的一部分水通过流入室230b排出，因此也可以不进行大幅减小向接水室230a的供水流量以免接水室230a被水充满而导致室内排尽空气的操作。由此,水容易从供水口221水势良好地落下，因此，容易在接水室230a内产生很多气泡。The water in the water receiving chamber 230a that has not flowed out from the outflow port 234 flows into the inflow chamber 230b, and is discharged to the water injection channel 250 from the discharge port 235 of the inflow chamber 230b. In this way, part of the water in the water receiving chamber 230a is discharged through the inflow chamber 230b, so it is not necessary to greatly reduce the water supply flow rate to the water receiving chamber 230a to prevent the water receiving chamber 230a from being filled with water and causing the room to exhaust air. . Accordingly, water tends to fall from the water supply port 221 with good momentum, and therefore, many air bubbles are easily generated in the water receiving chamber 230a.
需要说明的是，接水室230a被设为使蓄留的水充分被所产生的气泡充满的容积为好。若如此设定，则能从多个流出口234流出充分含有气泡的水。It should be noted that the water receiving chamber 230a is preferably set to a volume such that the stored water is sufficiently filled with the generated air bubbles. If set in this way, water sufficiently containing air bubbles can flow out from the plurality of outflow ports 234 .
如图7的(b)所示，在洗涤剂盒110内，洗涤剂与从接水室230a供给来的水混合而生成洗涤剂液，洗涤剂液的液位逐渐上升。所产生的洗涤剂泡沫比洗涤剂液轻，因此存在于洗涤剂液的水面附近。当液位超过虹吸管117的上端而洗涤剂液流入虹吸管117时，虹吸机构部S1开始排出洗涤剂液，洗涤剂液通过虹吸机构部S1向注水路250排出。洗涤剂液流过注水路250而前往注水口251。As shown in FIG. 7( b ), in detergent box 110 , detergent is mixed with water supplied from water receiving chamber 230 a to generate detergent liquid, and the liquid level of detergent liquid gradually rises. The generated detergent foam is lighter than the detergent liquid, so it exists near the water surface of the detergent liquid. When the liquid level exceeds the upper end of the siphon pipe 117 and the detergent liquid flows into the siphon pipe 117, the siphon mechanism part S1 starts to discharge the detergent liquid, and the detergent liquid is discharged to the water injection channel 250 through the siphon mechanism part S1. The detergent liquid flows through the water injection channel 250 to the water injection port 251 .
虹吸机构部S1对洗涤剂液的排出流量被设为比水向洗涤剂盒110内的供给流量少，洗涤剂盒110内的洗涤剂液的液位持续上升并达到溢水口118的高度。由此，洗涤剂液还会从溢水口118向注水路250排出。在来自接水室230a的水的落下位置附近大量产生的洗涤剂泡沫也前往溢水口118。The discharge flow rate of the detergent liquid by the siphon mechanism S1 is set to be smaller than the water supply flow rate into the detergent box 110 , and the liquid level of the detergent liquid in the detergent box 110 continues to rise and reaches the height of the overflow port 118 . Accordingly, the detergent liquid is also discharged from the overflow port 118 to the water injection path 250 . Detergent bubbles generated in large quantities near the drop position of the water from the water receiving chamber 230 a also go to the overflow port 118 .
此时，洗涤剂泡沫流过盖部142的檐部144的上方，进而通过盖部142的 倾斜面143被引导向虹吸帽141的上方。然后，洗涤剂泡沫流过虹吸帽141的上方，从溢水口118向注水路250排出。如此一来，洗涤剂泡沫不受虹吸帽141、盖部142妨碍地顺畅地流向溢水口118。At this time, the detergent foam flows over the eaves 144 of the cover 142, and then is guided to the top of the siphon cap 141 by the inclined surface 143 of the cover 142. Then, the detergent bubbles flow over the siphon cap 141 and are discharged from the overflow port 118 to the water injection path 250 . In this way, the detergent bubbles smoothly flow to the overflow port 118 without being hindered by the siphon cap 141 and the cover part 142 .
由此，能将在洗涤剂盒110内生成的洗涤剂泡沫良好地向注水路250排出。此外，能使洗涤剂泡沫不易在盖部142的里侧等残留。而且，洗涤剂泡沫通过盖部142的倾斜面143被引导向上方而从虹吸机构部S1排出，因此，能够使洗涤剂泡沫不易因前往洗涤剂盒110的底面的洗涤剂液的流动而被吸入洗涤剂液中。由此，能够使洗涤剂泡沫不易消失。Accordingly, the detergent foam generated in detergent box 110 can be well discharged to water injection path 250 . In addition, it is possible to make it difficult for detergent bubbles to remain on the back side of cover portion 142 and the like. Furthermore, since the detergent foam is guided upward by the inclined surface 143 of the cover part 142 and discharged from the siphon mechanism part S1, it is possible to prevent the detergent foam from being sucked by the flow of detergent liquid going to the bottom surface of the detergent box 110. in detergent solution. Thereby, it is possible to make it difficult for the detergent foam to disappear.
从溢水口118排出的洗涤剂泡沫与从溢水口118排出的洗涤剂液一起流过注水路250。此时，洗涤剂泡沫被从流入室230b的排出口235排出到溢水口118的上游的水冲走。由此，洗涤剂泡沫顺畅地流过注水路250而前往注水口251，洗涤剂泡沫不易在注水路250残留。The detergent foam discharged from the overflow port 118 flows through the water injection path 250 together with the detergent liquid discharged from the overflow port 118 . At this time, the detergent foam is washed away by the water discharged from the discharge port 235 of the inflow chamber 230b to the upstream of the overflow port 118 . Accordingly, the detergent foam flows smoothly through the water injection channel 250 to the water injection port 251 , and the detergent foam is less likely to remain in the water injection channel 250 .
流过注水路250的洗涤剂液和洗涤剂泡沫从注水口251向前方流出，碰到偏转体170而流向下方，向洗涤脱水桶22内流下。如此一来，不仅向洗涤脱水桶22供给含有洗涤剂的水，还供给很多洗涤剂泡沫。洗涤剂泡沫与洗涤物接触，由此洗涤剂容易浸透至洗涤物。由此，能在清洗过程中提高洗涤物的洗净性能。The detergent liquid and detergent foam flowing through the water injection channel 250 flow forward from the water injection port 251 , hit the deflector 170 , flow downward, and flow down into the washing and dehydrating tub 22 . In this way, not only water containing detergent but also a lot of detergent foam is supplied to washing and dehydrating tub 22 . The detergent bubbles come into contact with the laundry, whereby the detergent easily penetrates into the laundry. Thereby, the cleaning performance of the laundry can be improved during the cleaning process.
当第一供水阀61关闭而供水结束时，之后，洗涤剂盒110内的几乎全部洗涤剂液会通过虹吸机构部S1从洗涤剂盒110排出。When the first water supply valve 61 is closed and the water supply ends, almost all the detergent liquid in the detergent box 110 will be discharged from the detergent box 110 through the siphon mechanism part S1.
投入到柔顺剂盒120内的柔顺剂在漂洗过程的供水时被供给向洗涤脱水桶22。第二供水阀62开放，通过第二供水路64向注水口部200供水。供给来的水从供水口222导入到水路240a，流过水路240a并从流出口242向柔顺剂盒120内流出。流出至柔顺剂盒120内的水与柔顺剂混合而生成柔顺剂液。柔顺剂液通过虹吸机构部S2和溢水口128向注水路250排出，流过注水路250而来到洗涤脱水桶22。当第二供水阀62关闭而供水结束时，之后，柔顺剂盒120内的几乎全部柔顺剂液会通过虹吸机构部S2从柔顺剂盒120排出。The softener put into the softener box 120 is supplied to the washing and dehydrating tub 22 during the water supply in the rinsing process. The second water supply valve 62 is opened, and water is supplied to the water inlet portion 200 through the second water supply path 64 . The supplied water is introduced into water channel 240 a from water supply port 222 , flows through water channel 240 a , and flows out into softener box 120 from outflow port 242 . The water flowing out into the softener box 120 is mixed with the softener to generate a softener liquid. The softener liquid is discharged to the water injection path 250 through the siphon mechanism part S2 and the overflow port 128 , flows through the water injection path 250 , and reaches the washing and dehydration tub 22 . When the second water supply valve 62 is closed and the water supply ends, almost all the conditioner liquid in the conditioner box 120 will be discharged from the conditioner box 120 through the siphon mechanism part S2.
＜实施方式的效果＞<Effects of the implementation>
根据本实施方式，通过使含有在接水室230a产生的气泡的水向投入了洗涤剂的洗涤剂盒110内流下，能使洗涤剂容易起泡，因此，能在洗涤剂盒110内 充分生成洗涤剂泡沫，能向洗涤脱水桶22供给所生成的洗涤剂泡沫。由此，洗涤剂容易浸透至洗涤脱水桶22内的洗涤物，能期待洗净性能的提高。而且，由于未在洗涤剂盒110之外另设用于生成洗涤剂泡沫的发泡室，因此洗涤剂投入装置50的尺寸不易变大。According to this embodiment, by making the water containing the air bubbles generated in the water receiving chamber 230a flow down into the detergent box 110 into which the detergent has been put, the detergent can be easily foamed, and therefore, sufficient bubbles can be generated in the detergent box 110. The detergent foam can be supplied to the washing and dehydrating tub 22 so as to generate the detergent foam. Thereby, the detergent easily penetrates into the laundry in the washing and dehydrating tub 22, and an improvement in cleaning performance can be expected. Furthermore, since a foaming chamber for generating detergent foam is not provided separately from detergent box 110, the size of detergent input device 50 is less likely to increase.
而且，根据本实施方式，未从流出口234流出的接水室230a内的水流入到流入室230b，从流入室230b的排出口235向注水路250排出而供给向洗涤脱水桶22。由此，可以不大幅减小向接水室230a的供水流量，因此水容易从供水口221水势良好地落下，容易在接水室230a内产生很多气泡。而且，向洗涤脱水桶22供水所需的时间不易变长。Furthermore, according to the present embodiment, the water in the water receiving chamber 230a that has not flowed out from the outlet 234 flows into the inflow chamber 230b, is discharged from the discharge port 235 of the inflow chamber 230b to the water injection path 250, and is supplied to the washing and dehydrating tub 22. Accordingly, the flow rate of the water supplied to the water receiving chamber 230a does not need to be greatly reduced, so water tends to fall from the water supply port 221 with good momentum, and many air bubbles tend to be generated in the water receiving chamber 230a. Furthermore, the time required to supply water to the washing and dehydrating tub 22 is less likely to be prolonged.
而且，根据本实施方式，排出到注水路250的洗涤剂泡沫被从流入室230b的排出口235排出到溢水口118的上游的水冲走。由此，洗涤剂泡沫顺畅地流过注水路250，洗涤剂泡沫不易在注水路250残留。Also, according to the present embodiment, the detergent foam discharged to the water injection path 250 is washed away by the water discharged from the discharge port 235 of the inflow chamber 230 b to the upstream of the overflow port 118 . Accordingly, the detergent foam flows smoothly through the water injection path 250 , and the detergent foam is less likely to remain in the water injection path 250 .
而且，根据本实施方式，洗涤剂泡沫被盖部142的倾斜面143引导向虹吸帽141的上方并流过虹吸帽141的上方从溢水口118排出。由此，能不受虹吸帽141、盖部142妨碍地将在洗涤剂盒110内生成的洗涤剂泡沫良好地从溢水口118排出。Moreover, according to the present embodiment, the detergent bubbles are guided to the upper side of the siphon cap 141 by the inclined surface 143 of the cover portion 142 and flow through the upper side of the siphon cap 141 to be discharged from the overflow port 118 . Thereby, the detergent bubbles generated in detergent box 110 can be well discharged from overflow port 118 without being hindered by siphon cap 141 and cover portion 142 .
